为降低等离子体显示器(PDP)的寻址功耗,在分析PDP寻址功耗和图像信息在各子场分布特征的基础上,根据人眼视觉在不同背景亮度下对图像信息感知能力不同的特点,提出了子场数据自适应优化低功耗寻址方法。该方法在图像质量变化不影响视觉感知的情况下,根据图像寻址功耗的预设目标和实际值,自适应选择寻址功耗的优化级别,通过减少低权重子场数据变化率来降低PDP寻址功耗。该方法仅需对寻址数据的算法进行优化,无需改动硬件和驱动波形,在50英寸WXGA单扫PDP模组上对IEC标准动态视频的寻址功耗进行测试,结果表明,该方法可使IEC标准动态视频的寻址功耗平均降低8.17%,最大降低25.8W。
In order to reduce the address power consumption of plasma display panel (PDP), based on analyzing the distribution characteristics of PDP addressing power consumption and image information in each sub-field, according to different visual effects of human eyes on the perception of image information under different background brightness Characteristics, proposed sub-field data adaptive optimization low-power addressing method. This method adaptively chooses the optimized level of addressing power consumption according to the preset target and actual value of image addressing power consumption under the condition that the image quality change does not affect the visual perception, and reduces by reducing the rate of change of the low-weight sub-field data PDP addressing power consumption. This method only needs to optimize the algorithm of addressing data, and test the addressing power consumption of IEC standard dynamic video in the 50-inch WXGA single-scan PDP module without changing the hardware and driving waveforms. The results show that this method can make The addressing power consumption of IEC standard dynamic video is reduced by 8.17% on average, and the maximum reduction is 25.8W.
